I probably use the Comparadun/Sparkle Dun for at least 75% of my dry fly patterns these days. I find them to be extremely effective.
I think one version that Caucci and Nastasi detail in their book is not used that much. It is the Hackled Comparadun. It is for faster water and also allows a bit of "skittering". Anyway, I am tying some up for a stretch of water with riffles.
